Abstract

This research aim was to determine the optimal salinity of crumb rubber wastewater as a medium for growth and production of Spirulina sp. Crumb rubber wastewater salinity adjusted to 0 ppt, 10 ppt, 20 ppt, 30 ppt, and 40 ppt (75 % v/v) and then 25% v/v inoculum of Spirulina sp. cultivated in an open pond reactor with a worked volume of 5 L for 7 days. The results of this study indicated that the most optimal salinity was 20 ppt. The yield was dry biomass up to 0.579 g / L and cell density level reaching 11,330 cells / mL and able to reduce N-total content by 69.3% and P-PO4 by 50%. The biomass had protein content of 42.72%, fat content of 5.05%, ash content of 36.79%, water content of 11% and carbohydrate content of 4.42%. Keyword : Crumb Rubber Wastewater, Microalga, Salinity, Spirulina sp.
